Cabozantinib (liver and kidney cancer)
(ka'' boe zan' ti nib)
Brand Name(s): , Cabometyx®
WHY is this medicine prescribed?
Cabozantinib (Cabometyx) is used to treat advanced renal cell carcinoma (RCC; a type of cancer that begins in the cells of the kidneys). It is also used to treat hepatocellular carcinoma (HCC; a type of liver cancer) in people who were previously treated with sorafenib (Nexafar). Cabozantinib (Cabometyx) is in a class of medications called kinase inhibitors. It works by blocking the action of an abnormal protein that signals cancer cells to multiply. This helps slow or stop the spread of cancer cells.
Cabozantinib is also available as a capsule (Cometriq) to treat a certain type of thyroid cancer. This monograph only gives information about cabozantinib tablets (Cabometyx) for advanced RCC or HCC. If you are using this medication for thyroid cancer, read the monograph entitled cabozantinib (thyroid cancer).
